Using camera on computer simulation controller

ABSTRACT

A computer simulation controller includes a camera that can be used to image a display on which a computer simulation, controlled by the controller, can be presented. The camera images information on the display, such as display identification (ID), and sends the information to a server streaming the simulation. Based on the information, the server knows to which display to stream the simulation.

FIELD

The application relates to the use of cameras on computer simulation controllers.

BACKGROUND

Video simulation such as video gaming is growing in popularity. As understood herein, simulations increasingly are played by streamlining the simulations from one or more servers over the Internet.

SUMMARY

As also understood herein, it would be convenient for a user to easily switch display screens on which a streamed simulation is being played with a controller using attributes of the controller to communicate directly with the server streamlining the simulation, so that display screens can be controller-agnostic and the controller used for credentialing the user to the server as well as for display screen selection.

Accordingly, a system includes at least one computer storage that is not a transitory signal and that in turn includes instructions executable by at least one processor to receive at least one image from a camera of a simulation controller. The image is of at least a portion of a display device (DD) and indicates an identification (ID) of the DD. The instructions are executable to send the image to a simulation server on a communication path that does not include the DD. The communication path typically is at least in part wireless. The instructions are executable to send user credentials stored in the controller to the simulation server, with the server streaming, based on the ID of the DD received from the simulation controller, a simulation to the DD for presentation thereof under control of the simulation controller responsive to the credentials being valid.

The processor and computer storage can be implemented by the simulation controller.

In examples, the simulation controller communicates with the simulation via a wireless access point (AP) or router or a 5G controller.

In non-limiting examples, the instructions can be executable to provide the simulation server with color information from the simulation controller usable by the simulation server to adjust a color characteristic of the simulation. In non-limiting examples, the instructions can be executable to provide the simulation server with latency information from the simulation controller usable by the simulation server to adjust a delay of the simulation.

In another aspect, a system includes at least one computer simulation controller configured to wirelessly communicate with a network portal, at least one simulation server configured to communicate with the simulation controller through the network portal, and at least one display device configured to receive at least one computer simulation from the simulation server along with control signals from the simulation server generated by the simulation controller and provided to the simulation server through the network portal. The system also includes at least one camera on the simulation controller to image information on the display device indicating at least an identification (ID) of the display device, and the simulation controller sends the ID to the simulation server.

In another aspect, a method includes imaging a display on which a computer simulation, controlled by a simulation controller, is presentable. The method includes sending a result of the imaging to a server streaming the simulation via a network portal, and receiving, in response to the sending, the simulation for play thereof on the display. The method also includes controlling the display using the simulation controller by sending commands input to the simulation to the server via the network portal.

The details of the present application, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:

Now specifically referring to FIG. 1, an example system 10 is shown, which may include one or more of the example devices mentioned above and described further below in accordance with present principles. The first of the example devices included in the system 10 is a consumer electronics (CE) device such as an audio video device (AVD) 12 such as but not limited to an Internet-enabled TV with a TV tuner (equivalently, set top box controlling a TV). However, the AVD 12 alternatively may be an appliance or household item, e.g. computerized Internet enabled refrigerator, washer, or dryer. The AVD 12 alternatively may also be a computerized Internet enabled (“smart”) telephone, a tablet computer, a notebook computer, a wearable computerized device such as e.g. computerized Internet-enabled watch, a computerized Internet-enabled bracelet, other computerized Internet-enabled devices, a computerized Internet-enabled music player, computerized Internet-enabled head phones, a computerized Internet-enabled implantable device such as an implantable skin device, etc. Regardless, it is to be understood that the AVD 12 is configured to undertake present principles (e.g. communicate with other CE devices to undertake present principles, execute the logic described herein, and perform any other functions and/or operations described herein).

Accordingly, to undertake such principles the AVD 12 can be established by some or all of the components shown in FIG. 1. For example, the AVD 12 can include one or more displays 14 that may be implemented by a high definition or ultra-high definition “4K” or higher flat screen and that may be touch-enabled for receiving user input signals via touches on the display. The AVD 12 may include one or more speakers 16 for outputting audio in accordance with present principles, and at least one additional input device 18 such as e.g. an audio receiver/microphone for e.g. entering audible commands to the AVD 12 to control the AVD 12. The example AVD 12 may also include one or more network interfaces 20 for communication over at least one network 22 such as the Internet, an WAN, an LAN, etc. under control of one or more processors 24. A graphics processor 24A may also be included. Thus, the interface 20 may be, without limitation, a Wi-Fi transceiver, which is an example of a wireless computer network interface, such as but not limited to a mesh network transceiver. It is to be understood that the processor 24 controls the AVD 12 to undertake present principles, including the other elements of the AVD 12 described herein such as e.g. controlling the display 14 to present images thereon and receiving input therefrom. Furthermore, note the network interface 20 may be, e.g., a wired or wireless modem or router, or other appropriate interface such as, e.g., a wireless telephony transceiver, or Wi-Fi transceiver as mentioned above, etc.

In addition to the foregoing, the AVD 12 may also include one or more input ports 26 such as, e.g., a high definition multimedia interface (HDMI) port or a USB port to physically connect (e.g. using a wired connection) to another CE device and/or a headphone port to connect headphones to the AVD 12 for presentation of audio from the AVD 12 to a user through the headphones. For example, the input port 26 may be connected via wire or wirelessly to a cable or satellite source 26 a of audio video content. Thus, the source 26 a may be, e.g., a separate or integrated set top box, or a satellite receiver. Or, the source 26 a may be a game console or disk player containing content such as computer game software and databases. The source 26 a when implemented as a game console may include some or all of the components described below in relation to the CE device 44.

The AVD 12 may further include one or more computer memories 28 such as disk-based or solid-state storage that are not transitory signals, in some cases embodied in the chassis of the AVD as standalone devices or as a personal video recording device (PVR) or video disk player either internal or external to the chassis of the AVD for playing back AV programs or as removable memory media. Also in some embodiments, the AVD 12 can include a position or location receiver such as but not limited to a cellphone receiver, GPS receiver and/or altimeter 30 that is configured to e.g. receive geographic position information from at least one satellite or cellphone tower and provide the information to the processor 24 and/or determine an altitude at which the AVD 12 is disposed in conjunction with the processor 24. However, it is to be understood that another suitable position receiver other than a cellphone receiver, GPS receiver and/or altimeter may be used in accordance with present principles to e.g. determine the location of the AVD 12 in e.g. all three dimensions.

Continuing the description of the AVD 12, in some embodiments the AVD 12 may include one or more cameras 32 that may be, e.g., a thermal imaging camera, a digital camera such as a webcam, and/or a camera integrated into the AVD 12 and controllable by the processor 24 to gather pictures/images and/or video in accordance with present principles. Any of the cameras described herein may employ the high spectrum camera example or multiple examples described further below.

Also included on the AVD 12 may be a Bluetooth transceiver 34 and other Near Field Communication (NFC) element 36 for communication with other devices using Bluetooth and/or NFC technology, respectively. An example NFC element can be a radio frequency identification (RFID) element. Zigbee also may be used.

Further still, the AVD 12 may include one or more auxiliary sensors 37 (e.g., a motion sensor such as an accelerometer, gyroscope, cyclometer, or a magnetic sensor, an infrared (IR) sensor, an optical sensor, a speed and/or cadence sensor, a gesture sensor (e.g. for sensing gesture command), etc.) providing input to the processor 24. The AVD 12 may include an over-the-air TV broadcast port 38 for receiving OTA TV broadcasts providing input to the processor 24. In addition to the foregoing, it is noted that the AVD 12 may also include an infrared (IR) transmitter and/or IR receiver and/or IR transceiver 42 such as an IR data association (IRDA) device. A battery (not shown) may be provided for powering the AVD 12.

Still referring to FIG. 1, in addition to the AVD 12, the system 10 may include one or more other CE device types. In one example, a first CE device 44 may be used to send computer game audio and video to the AVD 12 via commands sent directly to the AVD 12 and/or through the below-described server while a second CE device 46 may include similar components as the first CE device 44. In the example shown, the second CE device 46 may be configured as a VR headset worn by a player 47 as shown, or a hand-held game controller manipulated by the player 47. In the example shown, only two CE devices 44, 46 are shown, it being understood that fewer or greater devices may be used.

In the example shown, to illustrate present principles all three devices 12, 44, 46 are assumed to be members of an entertainment network in, e.g., a home, or at least to be present in proximity to each other in a location such as a house. However, present principles are not limited to a particular location, illustrated by dashed lines 48, unless explicitly claimed otherwise.

The example non-limiting first CE device 44 may be established by any one of the above-mentioned devices, for example, a portable wireless laptop computer or notebook computer or game controller (also referred to as “console”), and accordingly may have one or more of the components described below. The first CE device 44 may be a remote control (RC) for, e.g., issuing AV play and pause commands to the AVD 12, or it may be a more sophisticated device such as a tablet computer, a game controller communicating via wired or wireless link with the AVD 12, a personal computer, a wireless telephone, etc.

Accordingly, the first CE device 44 may include one or more displays 50 that may be touch-enabled for receiving user input signals via touches on the display. The first CE device 44 may include one or more speakers 52 for outputting audio in accordance with present principles, and at least one additional input device 54 such as e.g. an audio receiver/microphone for e.g. entering audible commands to the first CE device 44 to control the device 44. The example first CE device 44 may also include one or more network interfaces 56 for communication over the network 22 under control of one or more CE device processors 58. A graphics processor 58A may also be included. Thus, the interface 56 may be, without limitation, a Wi-Fi transceiver, which is an example of a wireless computer network interface, including mesh network interfaces. It is to be understood that the processor 58 controls the first CE device 44 to undertake present principles, including the other elements of the first CE device 44 described herein such as e.g. controlling the display 50 to present images thereon and receiving input therefrom. Furthermore, note the network interface 56 may be, e.g., a wired or wireless modem or router, or other appropriate interface such as, e.g., a wireless telephony transceiver, or Wi-Fi transceiver as mentioned above, etc.

In addition to the foregoing, the first CE device 44 may also include one or more input ports 60 such as, e.g., a HDMI port or a USB port to physically connect (e.g. using a wired connection) to another CE device and/or a headphone port to connect headphones to the first CE device 44 for presentation of audio from the first CE device 44 to a user through the headphones. The first CE device 44 may further include one or more tangible computer readable storage medium 62 such as disk-based or solid-state storage. Also in some embodiments, the first CE device 44 can include a position or location receiver such as but not limited to a cellphone and/or GPS receiver and/or altimeter 64 that is configured to e.g. receive geographic position information from at least one satellite and/or cell tower, using triangulation, and provide the information to the CE device processor 58 and/or determine an altitude at which the first CE device 44 is disposed in conjunction with the CE device processor 58. However, it is to be understood that another suitable position receiver other than a cellphone and/or GPS receiver and/or altimeter may be used in accordance with present principles to e.g. determine the location of the first CE device 44 in e.g. all three dimensions.

Continuing the description of the first CE device 44, in some embodiments the first CE device 44 may include one or more cameras 66 that may be, e.g., a thermal imaging camera, a digital camera such as a webcam, and/or a camera integrated into the first CE device 44 and controllable by the CE device processor 58 to gather pictures/images and/or video in accordance with present principles. Also included on the first CE device 44 may be a Bluetooth transceiver 68 and other Near Field Communication (NFC) element 70 for communication with other devices using Bluetooth and/or NFC technology, respectively. An example NFC element can be a radio frequency identification (RFID) element.

Further still, the first CE device 44 may include one or more auxiliary sensors 72 (e.g., a motion sensor such as an accelerometer, gyroscope, cyclometer, or a magnetic sensor, an infrared (IR) sensor, an optical sensor, a speed and/or cadence sensor, a gesture sensor (e.g. for sensing gesture command), etc.) providing input to the CE device processor 58. The first CE device 44 may include still other sensors such as e.g. one or more climate sensors 74 (e.g. barometers, humidity sensors, wind sensors, light sensors, temperature sensors, etc.) and/or one or more biometric sensors 76 providing input to the CE device processor 58. In addition to the foregoing, it is noted that in some embodiments the first CE device 44 may also include an infrared (IR) transmitter and/or IR receiver and/or IR transceiver 78 such as an IR data association (IRDA) device. A battery (not shown) may be provided for powering the first CE device 44. The CE device 44 may communicate with the AVD 12 through any of the above-described communication modes and related components.

The second CE device 46 may include some or all of the components shown for the CE device 44. Either one or both CE devices may be powered by one or more batteries.

Now in reference to the afore-mentioned at least one server 80, it includes at least one server processor 82, at least one tangible computer readable storage medium 84 such as disk-based or solid-state storage, and at least one network interface 86 that, under control of the server processor 82, allows for communication with the other devices of FIG. 1 over the network 22, and indeed may facilitate communication between servers and client devices in accordance with present principles. Note that the network interface 86 may be, e.g., a wired or wireless modem or router, Wi-Fi transceiver, or other appropriate interface such as, e.g., a wireless telephony transceiver.

Accordingly, in some embodiments the server 80 may be an Internet server or an entire server “farm” and may include and perform “cloud” functions such that the devices of the system 10 may access a “cloud” environment via the server 80 in example embodiments for, e.g., network gaming applications. Or, the server 80 may be implemented by one or more game consoles or other computers in the same room as the other devices shown in FIG. 1 or nearby.

Further to what has been alluded to above, logical blocks, modules, and circuits described below can be implemented or performed with a general-purpose processor, a digital signal processor (DSP), a field programmable gate array (FPGA) or other programmable logic device such as an application specific integrated circuit (ASIC), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A processor can be implemented by a controller or state machine or a combination of computing devices. Thus, the methods herein may be implemented as software instructions executed by a processor, suitably configured application specific integrated circuits (ASIC) or field programmable gate array (FPGA) modules, or any other convenient manner as would be appreciated by those skilled in those art. Where employed, the software instructions may be embodied in a non-transitory device such as a hard disk drive, CD ROM or Flash drive. The software code instructions may also be downloaded over the Internet.

FIG. 2 illustrates a wireless simulation controller 200 such as a computer game controller with plural control elements 202 such as keys, rocker elements, and the like. The controller may include a headphone jack 203 with volume control buttons V that can control audio volume level of the audio played back on the headphone jack and/or on the AVD and/or on the simulation server, to improve the user experience.

In the example shown, one or more cameras 204 are on the controller 200 (and if desired, one or more microphones 205) to communicate image signals (and audio signals from the microphone) to one or more processors 206 accessing instructions and data on one or more computer memories 208. The processor 206 can communicate, using one or more wireless transceivers 210 such as a Wi-Fi transceiver, 5G transceiver, Bluetooth transceiver, or wireless telephony transceiver or combinations thereof along a wireless link 212 with a network portal 214 such as a router, a 5G controller, or an Access Point (AP). Through the network portal 214 the controller 200 communicates with one or more simulation servers 216 on a wide area network such as the Internet, for purposes to be shortly disclosed. The controller 200 may be associated with its own network address and thus be directly addressable by the server 216, and may also store, e.g., on the memory 208, user credentials input to the controller 200 by any appropriate means, e.g., by manipulation of the control elements 202 or via Bluetooth from a wireless communication device or other technique.

The controller 200 is programmed to receive simulation commands generated by manipulation of the control elements 202 and send signals representing those commands to the server 216. In turn, the server 216 streams, under control of the commands input to the controller 200, one or more computer simulations such as computer games to one or more audio video devices (AVD) 218 such as an Internet-enabled TV with its own network address. Information 220 indicating the identification of the AVD, which may include or be correlated with a network address of the AVD, may be presented on the display of the AVD as shown, e.g., in the form of a bar code or quick response (QR) code or other text or symbol representation, for imaging by the camera 204 of the controller 200.

Also, the controller may include an infrared (IR) transceiver 222 other transceiver that can communicate with the AVD, so that the controller acts as a remote controller for the AVD powering on the capable device and launching an application, controlling volume level, etc.

FIG. 3 illustrates an alternate system in which a controller 300 without a camera may be paired, e.g., via Bluetooth with a wireless communication device 302 that has a camera 304 for imaging the identification information 308 on an AVD 308, with the wireless communication device 302 sending controller commands and information 306 to a simulation server 310 for controlling the streamlining of a simulation to the AVD 308.

The devices in FIGS. 2 and 3 may incorporate some or all of the various components shown in FIG. 1 and described above. In FIGS. 2 and 3, the AVDs can be game-controller-agnostic, which makes the integration of present principles simple in that the AVD is only being used as a dummy-streaming-display. The camera 202 on the controller 200 makes the process even simpler as divulged below.

Prior to describing FIG. 4, present principles recognize that simulation streamlining from a network server implicates latency challenges. From user's perspective, the latency may be thought of as the delay from input to the game controller to an observed reaction on screen to the input. More rigorously, without present principles Total Latency=(Game controller processing latency)+(Game controller to TV application connection latency)+(TV uplink processing latency)+(TV to streaming server connection latency)+(Streaming server processing latency)+(Streaming server to TV connection latency)+(TV display processing latency). However, because present principles provide a game controller which has a low latency network (e.g., Wi-Fi) connection which will enable the controller to communicate directly with the streaming server, the overall total latency is reduced.

FIG. 4 illustrates example logic consistent with present principles. For purposes of disclosure, assume that a user of the controller 200 whose credentials have been input to the controller goes to a friend's place at which an AVD such as the AVD 200 is implemented by a “smart TV” or “PC computer” or “Tablet computer” or large LED billboard screen. At block 400, the controller is connected to a simulation server via, e.g., Wi-Fi with internet access. At this point, an instance of the streaming server is reserved for the user.

Moving to block 402, the user launches a game streaming app on screen or the app is pre-loaded on the screen of the AVD. Proceeding to block 404, under control of the app the AVD presents the information 220, which is imaged by the camera 204 of the controller 200 (or in the embodiment of FIG. 3, the camera 304 of the assistant device 302). The user can manipulate a key on the controller 200 to activate the camera to pair the screen with the instance of streaming server as follows. The captured information 220 is sent to the simulation server at block 406 along with the user credentials to permit play of the simulation. At this point, the server streams, at block 408, the simulation to the AVD and a user can use the controller 200 to control the instance of the streaming server and the AVD, which is temporarily paired with the instance of the streaming server to display the simulation content. Play of the simulation is controlled at block 410 by a user manipulating the controller 200 to send control signals to the server 216 through the network portal 214.

Should a user desire to move physical location, the user can pause the simulation on the current location, move to a new location, and image a new information code 220 on a new AVD using the camera 204 of the controller 200 at block 412. The new AVD ID information is sent at block 414 to the server via a (typically new) network portal, causing the simulation server at block 416 to disconnect streamlining from the original AVD and commence streaming (in a pause state if desired) to the new (substitute) AVD. The server may commence play of the simulation on the new (substitute) AVD at a point in the simulation at which the simulation was stopped being streamed to the first AVD.

By not storing the user credential/preference on a screen device but rather on the portable wireless controller 200, the user is free to roam around all the AVDs he or she might wish, playing the simulation on each. For instance, a user could be playing game at a friend's TV. On the way home, the user can switch play to a tablet computer. Upon arriving home, the user can continue playing on a large TV again. A user can then decide to demo the simulation at a convention center by running an application on a computer connected to a projector, and the controller scans the Barcode/QR code.

All these screen-to-screen transition do not require additional credential input.

In addition to the above, the camera 204 on the controller 200 may be used for (temporary or permanent) provisioning to an agnostic host. It may be used for tracking, and for capturing a social moment photo with other gamers. The camera may be used as a text input interface by utilizing OCR, in which a user can write the text and scan it. The camera may be used to point to printed text such as “http://www.psn.com/redeem=X2sTwvGe” which prompts the opening of a browser window. The camera may be used for prepaid card/digital purchase code redemption by scanning a text code or bar/QR code on the AVD and associated with a product or service sought to be purchased. The camera may be used for bar code reading for online shopping, and to add an online friend by scanning a printed Text/Bar/QR code or a smart phone device screen displaying the code.

The camera may be used as an optional button, by detecting a finger/palm covering the camera. By measuring brightness registered on camera input, it can also approximate the distance between the camera and the finger covering it.

In addition to the above, FIG. 5 shows that the camera 204 may be used to measure latency end-to-end. At block 500 the camera may image a latency pattern on the AVD and as soon as the processor 206 receiving the image recognizes the “pattern” on the screen, it will send trigger signal to the server at block 502. In response, at block 504 the server returns an acknowledgement pattern to the AVD, which is imaged by the camera 204 at block 506 to enable the processor 206 to calculate the time difference between, e.g., blocks 502 and 506. The “ack” pattern can be bar/QR code or simple solid color.

If desired, not only the latency of the video portion of the streaming service may be determined but also the audio portion, so that the server can adjust delays between audio and video streamlining to account for different latencies such that audio is synchronized with video at the AVD. At block 508 the microphone 205 may detect a tone correlated by the processor to a “start audio latency measurement” command. Moving to block 510, upon detection of the tone the processor sends a trigger to the server, which responds by sending an acknowledgement tone back to the AVD at block 512, which is sensed by the controller microphone at block 514 and used to determine a time differential as described above (e.g., the time difference between sending the trigger at block 510 and senses in the “ack” tone at block 514). The controller sends the audio and video latencies to the simulation server at block 516 via the network portal so that the server at block 518 may adjust audio and video streamlining of the simulation so as to synchronize audio with video when presented on the AVD.

FIG. 6 illustrates that the camera 204 may be used to provide the simulation server with color information from the simulation controller usable by the server to adjust a color characteristic of the simulation. This may include one or both of color calibration on the display device, and ambient color tone measurement (measure the color temperature of ambient light, bringing homogeneous or heterogeneous visual perception). Commencing at block 600, the camera 204 images the AVD which includes a representation of the color temperature of the display. In addition or alternatively, the ambient light level adjacent the AVD may be imaged.

Moving to block 602, the ambient light and/or color temperature information is sent to the server. At block 604 the server adjusts the video according to the color temperature of the AVD and/or ambient light. For example, for low levels of ambient light, the video may be adjusted to have less contrast while under high ambient light conditions the video may be adjusted to have relatively more contrast. Yet again, for an AVD color temp that is biased toward red, the server may adjust the color temperature of the video to be biased more toward blue, while for an AVD color temp that is biased toward blue, the server may adjust the color temperature of the video to be biased more toward red, to offset the color temperature bias of the AVD.

It will be appreciated that whilst present principals have been described with reference to some example embodiments, these are not intended to be limiting, and that various alternative arrangements may be used to implement the subject matter claimed herein.
